Phosphine (PH3) is a kind of chemical compound that is colorless but flammable and toxic. Pure phosphine becomes odorless, but some compounds have an extremely foul odor, such as garlic or rotten fish. Meanwhile, commercially produced phosphine gas is added to the garlic essence to detect leakage during use.
Phosphine, also known as hydrogen phosphite, is a very toxic gas and is lethal to humans, even at very low concentrations. In case of prolonged exposure, vision loss occurs in the eyes. The most important effect on the human body is irritation of the respiratory tract and chronic damage to the skeleton.
The most widely used area of phosphine gas is pesticide spraying. Phosphine is included in the formula of many pesticides used in the struggle against rodents and pests in cereals. In the textile industry, phosphine also acts as an intermediate in the synthesis of flame retardant chemicals for cotton fabrics.
Phosphine is a highly toxic gas for all humans, animals, plants, in short, all life forms. People should not be exposed to this gas even at very low amounts. Poisoning is usually caused by inhalation. Does not penetrate the skin through the body. The toxicity limit value was determined as 40 ppm for a working week of 0,3. Phosphine is among the most toxic pesticides. The toxic effect in pest control is reduced as the temperature decreases.
Our company performs phosphine (PH3) measurements within the scope of gas measurements. In these studies relevant legal regulations, standards and test methods published by local and foreign organizations. One of the standards used in these studies is:
- TS 3851 Phosphine residue determination in aluminum phosphide treated grain (spectrophotometric method)
This standard covers a spectrophotometric analysis method used to determine the amount of phosphine residue remaining in the stored cereals after spraying with aluminum phosphide.
In the meantime, our organization, ÖSAS Accreditation Agency, It is accredited according to TS EN ISO / IEC 17025 standard and the tests, measurement, analysis, inspection and inspection procedures and reports are accepted as valid in private and official audits.
